Technical Field
[0001] The present invention relates to the technical field of ventricular drainage, in particular to a ventricular drainage device. Background Art
[0002] External ventricular drainage is a common neurosurgical treatment method. CSF is drained to the outside of the body by placing a drainage tube through a burr hole or a cone-shaped hole in the skull to puncture the lateral ventricle. It is commonly used to treat acute hydrocephalus, intracranial hypertension, subarachnoid hemorrhage, intracranial infection, etc. Proper fixation and effective drainage of the ventricular drainage device are closely related to the prognosis of the disease and affect the occurrence of postoperative complications. The latest research and clinical guidelines emphasize the importance of external ventricular drainage management. Currently, the traditional method of fixing the drainage device is to fix it to the patient's bedside with a rope or tape.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.
[0032] Based on the actual clinical needs of neurosurgery, the card slot sliding and infrared surface positioning design are used to accurately locate the horizontal position of the ventricle and the zero point position of the drainage device, avoiding the influence of cerebrospinal fluid drainage fluctuation caused by changes in the bedside angle. When in use, place the fixed bracket at the bedside, turn on the infrared indicator pen in the front card slot ruler, and adjust the zero point position of the ruler to the height level of the ventricle through infrared horizontal positioning. The ventricular drainage device holder is installed in the side card slot. Fix the drainage device in the "concave" card slot and adjust it to the appropriate height according to the patient's actual condition to drain the cerebrospinal fluid. After determining the height, adjust the bedside angle by the infrared indicator pen. Quickly locate the surface ventricle level, and readjust the height of the ventricular drainage device based on the new ventricle level, so that the drainage height of the ventricular drainage device can be accurately repositioned to ensure that it remains unchanged every time the patient's bedside angle is changed. At the same time, a hook is designed at the top of the bracket for hanging nutrition bags that require enteral nutrition, and the nutrition pump can be fixed on the bracket, so that the height of the ventricular drainage device can be accurately adjusted, and it also has the function of installing enteral nutrition pumps and hanging nutrition bags. The design has left and right slots to facilitate drainage on different sides of the patient. The bracket can be removed after the patient's ventricular drainage tube is removed, and it can be installed and removed at any time, which is convenient for clinical operation.
[0033] The present invention provides a ventricular drainage device. The device comprises a movable unit, a display screen, and buttons. The movable unit is controlled to move on a column via the buttons. The relative distance the movable unit is to move can also be adjusted by operating the buttons, with the distance displayed in real time on the display screen. Furthermore, the movable unit can be more securely fixed to the column. The device incorporates a power-off electromagnet that generates magnetic flux only when power is off, securing the device to the column. This ensures secure fixation in the event of a sudden power outage or other power-off condition, improving safety during use. The device also comprises a laser pen and a rotating shaft. The laser pen can rotate about the rotating shaft, improving the device's adaptability and reducing placement requirements, enabling the laser pen to be positioned accurately. The output shafts of the laser pen and the motor are coaxial, and the motor is mounted in the middle of the housing and parallel to the horizontal plane. This ensures that the relative position of the laser pen remains unchanged when it is moved after positioning is complete, improving positioning accuracy. The device utilizes distance plus and distance minus buttons to adjust the movement distance and control the number of revolutions of the moving wheel, enabling precise control of the movement of the movable unit on the column.
[0034] Example 1
[0035] like Figures 1-4 As shown, a ventricular drainage device includes a column 1, a movable slot 3, a movable unit 2, a laser pen 5, a display screen 11, a button 12, and a fixed bracket. The movable slot 3 is mounted on both sides of the column 1. The movable unit 2 is mounted on the column 1 through the movable slot 3. The laser pen 5 is mounted on the fixed bracket. The fixed bracket is mounted on the movable unit 2. The display screen 11 and the button 12 are both mounted on the movable unit 2.
[0036] First, the mobile unit 2 is controlled to move on the column 1 by pressing the button 12 and positioned by the laser pen 5. After the positioning is completed, the relative distance to be moved by the mobile unit 2 is adjusted by pressing the button 12 and displayed on the display screen 11. Then the mobile unit 2 moves to the predetermined position and is firmly fixed.
[0037] The mobile unit includes a shell, a power-off type electromagnet 10, a motor 9 and a moving wheel 8. The shell is located on the surface of the column 1. The power-off type electromagnet 10 and the motor 9 are both installed in the shell. The motor 9 and the moving wheel 8 are connected and coaxial. The moving wheel 8 is installed in the moving groove 3.
[0038] The buttons 12 include an up key, a down key, a distance plus key, a distance minus key, and a confirmation key. The device also includes a control unit installed in the housing. The control unit is respectively connected to the power-off type electromagnet 10, the motor 9, the display screen 11, the up key, the down key, the distance plus key, the distance minus key, and the confirmation key. The display screen 11 and the buttons 12 are both installed on the housing of the mobile unit 2.
[0039] In this embodiment, the control unit of the present invention can realize the following process: first use the button 12 to press the up key or the down key, and then press the confirmation key to make the mobile unit 2 move up or down on the column 1 at a certain speed. After reaching the predetermined position, press the confirmation key again, the mobile unit 2 stops, and the initial positioning is completed; then, according to the relative distance between the drainage device and the initial positioning position, press the distance plus key or the distance minus key to set the relative distance to be adjusted. The adjustment range of each press of the distance plus key or the distance minus key is 1 cm, that is, the relative distance increases or decreases by 1 cm when the distance plus key or the distance minus key is pressed once. Then press the confirmation key, the mobile unit 2 moves up or down to the specified position and stops, and the relative distance to be adjusted is displayed in real time on the display screen 11 to prevent the mobile unit 2 from not moving to the correct position; in the mobile unit 2. Each time, the power-off type electromagnet 10 is cut off, so that it can generate magnetic chain for adsorption. Even if there is a sudden power outage, the electromagnet 10 will automatically generate magnetic force due to the power outage for adsorption, thereby improving safety in emergency situations. Accordingly, the side of the column 1 in contact with the power-off type electromagnet 10 is made of magnetic material to facilitate adsorption. The moving distance is calculated by controlling the number of revolutions of the moving wheel 8. Assuming that it needs to move up 10 cm and the cycle of the moving wheel 8 is 5 cm, it is sufficient to control the moving wheel 8 to rotate two revolutions. If it needs to move down 1 cm, it is sufficient to control the moving wheel 8 to rotate 1 / 5 of a revolution, thereby accurately controlling the moving distance. Using only the up key or the down key without using the distance plus key or the distance minus key means that the distance is adjusted in an unfixed manner, and the staff automatically chooses where to stop, thereby realizing both flexible adjustment and fixed adjustment.
[0040] The motor 9 is installed in the middle of the housing, and the motor 9 is parallel to the horizontal plane.
[0041] The output shafts of the laser pen 5 and the motor 9 are coaxial.
[0042] The fixing bracket includes a connecting rod 4 and a fixer 6, wherein the connecting rod 4 and the fixer 6 are connected, the connecting rod 4 is mounted on the housing, and the connecting rod 4 and the motor 9 are coaxial.
[0043] The connecting rod 4 and the output shaft of the motor 9 are coaxial.
[0044] In this embodiment, the laser pointer 5 is coaxial with the output shaft of the motor 9, and the motor is installed in the middle of the mobile unit 2. Figure 3 As shown, it is ensured that the position pointed by the laser pen 5 is the pointing position of the output shaft of the motor 9 and is also the pointing position in the middle of the mobile unit 2, thereby ensuring the reliability of the moving distance of the mobile unit 2.
[0045] The connecting rod includes a receiving cavity and a rotating shaft 7, and the laser pen 5 is installed in the receiving cavity via the rotating shaft 7. The rotating shaft 7 is installed in the middle of the receiving cavity.
[0046] The connecting rod 4 , the laser pen 5 and the fixer 6 are installed on one side of the motor 9 .
[0047] In this embodiment, the laser pen 5 can rotate horizontally 360° about the rotation axis 7, that is, no matter where the drainage device is installed, it can be well positioned, and the accommodating cavity can accommodate the laser pen 5 for easy storage.
[0048] The device further comprises a hook and a scale line, wherein the hook is mounted on the top of the column 1 and the scale line is mounted on the side of the column 1 .
[0049] In this embodiment, a hook is provided to facilitate hanging other objects, thereby improving practicality. Scale lines are provided on the side of the column 1 to facilitate estimating the moving distance of the mobile unit 2 and provide a reference. Scale lines can be provided on all sides of the column 1 for easy observation.
[0050] Example 2
[0051] like Figure 5 and Figure 6 As shown, a connecting rod 4, a laser pen 5 and a fixer 6 are respectively installed on both sides of the motor 9.
[0052] In this embodiment, a connecting rod 4, a laser pen 5 and a holder 6 are installed on both sides of the same motor 9. The connection relationship between the connecting rod 4, the laser pen 5 and the holder 6 is the same as that in Example 1, that is, a laser pen 5 is provided on both sides of the column 1. The laser pen 5 can illuminate the patients on the left and right sides respectively, thereby improving the flexibility of use of the present invention.
[0053] Example 3
[0054] Connecting rods 4 , laser pens 5 and fixers 6 are respectively installed on different motors 9 and are located on both sides of the column 1 .
[0055] In this embodiment, two movable slots 3 are provided on the column 1 of the present invention, that is, two movable wheels 8 and two motors 9 are required. The two motors 9 are located on both sides of the column 1. A set of connecting rods 4, a laser pen 5 and a holder 6 are installed on each motor 9. The specific connection method is shown in Example 1. The directions of the two sets of connecting rods 4, laser pen 5 and holder 6 are opposite, that is, similar to the two sides in Example 2, but they are not on the same motor 9. Similarly, the laser pen 5 can illuminate the patients on the left and right sides respectively, thereby improving the flexibility of use of the present invention.
